摘要：
The compression-permeability tests were carried out for sludges from seven water sources (river, reservoir, and groundwater) and one model sludge (aluminum hydroxide). Furthermore, the distribution of water content in the cake under constant rate dewatering was measured by slicing the cake to each thin cake layer, and liquid pressure drop is calculated using the results of compression-permeability tests. From these results the relations between sludge properties and compressive cake characteristics are discussed, and some fundamental knowledge to carry out the mechanical dewatering with small energy has been obtained.
